QUESTION
  ·  Mark as Answered

I still don’t fully understand the value of the blockchain. There is a ton of hype about the blockchain, bitcoin in general, and yes I do deeply understand its dynamics, it’s structure, how it works – but I still don’t understand why it’s really much more valuable then the typical client server model. Like…ok who cares about a distributed ledger, if I have a secure server that I can at least trust won’t get hacked? Blockchain sounds fancy, cool, but does it really alleviate the issue better then another startup saying our currency (or new currency servers) are the most secure servers ever created?

Good question. Don’t overestimate trust. Something like a “secure” server does not exist. This further assumes that the server owner acts truthfully. We see again and again that servers cannot be secured. Plus, the weakest link is the human (e.g. the administrators or employees) who, if an infrastructure is trust-based will provide a relatively easy attack surface (see “social engineering”). Another point is transparency in trust-based systems: how do you know Collaborizm has/is not compromised? I like this article: http://dupress.com/articles/blockchain-applications-and-trust-in-a-global-economy/ This article provides a nice analogy: https://aeon.co/essays/how-blockchain-will-revolutionise-far-more-than-money

+Jan Ahrend that’s fascinating and provided an answer I did not actually think existed. Now I get it…it’s the fact the client server model actually will always be a failure in some form. The power of the block chain is that it could potentially never be realistic to ever compromise the entire block chain. You clearly dig deep in Computer Science 😃

Steven Reubenstone Yes, it would require an attacker control more than 50% of the network’s computing power 😃
